INCI: Potassium Sorbate

Function: Preservative

Benefits: Prevents growth of fungi, bacteria and mold

The Science: Potassium Sorbate is a natural preservative derived from sorbic acid, which is originally found in the berries of the mountain ash (rowan) tree. As the potassium salt of sorbic acid, it effectively inhibits the growth of bacteria, fungi, and mold, helping to preserve the integrity and safety of skincare formulations. Its antimicrobial properties help extend shelf life while ensuring the product remains fresh and effective.

The Story: Potassium Sorbate is a preservative commonly used alongside sodium benzoate to enhance the shelf life of skincare products by preventing the growth of harmful bacteria, fungi, and mold.
